Hi-

I’m at a bit of a loss as to how to address and/or fix these errors.

The native input images are very good quality; the conversion to T1.mgz is fine; the brainmask.mgz is good, a bit of dura remained at the parietal/occipital region (very common); otherwise, the skull stripping is very clean.

The recon-all “finished” but with errors as expected. Processing “continued” to the end, but there is no output except in /mri and /touch.

Doing: #@# Skull Stripping

First under “Computing MAP estimate using 3481 samples...”

IFLAG= -1  LINE SEARCH FAILED. SEE DOCUMENTATION OF ROUTINE MCSRCH ERROR RETURN OF LINE SEARCH: INFO= 3 POSSIBLE CAUSES: FUNCTION OR GRADIENT ARE INCORRECT OR INCORRECT TOLERANCESoutof QuasiNewtonEMA: 005: -log(p) = 10327.2  tol 0.000010

Then several of the same under “EM alignment process ...”

Then again at “Computing MAP estimate using 2772 samples...”
